Abstract

A color filter substrate includes a color filter layer, a light-transmissive layer and a light-shielding layer. The light-transmissive layer is disposed between pixels and includes a side surface that forms a reflection surface. The light-shielding layer is laminated on the light-transmissive layer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A color filter substrate comprising:
 a light-transmissive substrate including an incident surface and an outgoing surface with respect to transmitted light; 
 a plurality of pixels in which a color filter layer is formed; 
 a protrusion portion that is disposed between the plurality of pixels on the outgoing surface of the light-transmissive substrate and partitions the color filter layer, the protrusion portion including:
 a light-transmissive layer comprising a light transmissive material that forms a reflective side surface, the reflective side surface being formed as an inclined surface and partitioning the color filter layer into at least a first color filter having a first color and a second color filter having a second color filter, the first color filter being directly adjacent to the second color filter; and 
 a light-shielding layer disposed such that the light-transmissive layer is disposed between the light-transmissive substrate and the light-shielding layer, 
 
 wherein
 the light-transmissive layer is disposed between at least the first color filter and the second color filter, 
 the light-transmissive layer disposed between the first color filter and the second color filter includes both a first strip-shaped light-transmissive layer and a second strip-shaped light-transmissive layer parallel to the first strip-shaped light-transmissive layer, 
 the first strip-shaped light-transmissive layer has a first side surface facing the first color filter and a second side surface facing the second strip-shaped light-transmissive layer, and 
 the second strip-shaped light-transmissive layer has a first side surface facing the second color filter and a second side surface facing the first strip-shaped light-transmissive layer. 
 
 
     
     
       2. The color filter substrate according to  claim 1 , wherein a side surface of the light-transmissive layer forms the reflective side surface by laminating the light-shielding layer on the side surface. 
     
     
       3. The color filter substrate according to  claim 2 ,
 wherein the reflective side surface is formed by laminating the light-shielding layer on the second side surface of the first strip-shaped light-transmissive layer oriented toward the second strip-shaped light-transmissive layer, and 
 wherein the reflective side surface is formed by laminating the light-shielding layer on the second side surface of the second strip-shaped light-transmissive layer oriented toward the first strip-shaped light-transmissive layer. 
 
     
     
       4. An electro-optic device comprising:
 a counter substrate including the color filter substrate according to  claim 1 ; 
 an element substrate in which a pixel transistor and a pixel electrode are formed; and 
 a liquid crystal layer interposed between the counter substrate and the element substrate. 
 
     
     
       5. An electronic apparatus comprising:
 the electro-optic device according to  claim 4 .
